| Abstract Two field experiments were conducted during 2023 and 2024 seasons at El- Qasasin district in Ismailia Governorate, Egypt to study the effect of four mixture of micronutrients concentrations namely tap water (control), 1500, 2500 and 3500 ppm as well as three concentrations of Glycine betaine namely tap water (control), 50, 100 and 150 mM on yield, its attributes and quality of sunflower (Helianthus annuus L.) Giza 102 variety under salinity stress conditions in loomy sandy soils of Ismailia Governorate, Egypt. Increasing concentration of micronutrients up to 3500 ppm significantly increased plant height, stem diameter, head diameter, hundred seed weight, seed weight per head and seed, straw and oil yields per fad as well as seed oil percentage of sunflower. Increasing Glycine betaine concentration up to 100 mM statistically increased all aforementioned characters. The interaction between mixtures of micronutrients and Glycine betaine affected significantly all aforementioned traits. The highest values of these characters produced from sunflower plants sprayed with 3500 ppm mixture of micronutrients and 100 mM Glycine betaine. | ||||
